BACKGROUND: Our previous studies have found that Wumei Pills can regulate the intestinal flora to inhibit chemotherapy-induced intestinal mucositis (CIM). However, there is still insufficient evidence to confirm that intestinal flora is the main link in the regulation of CIM by Wumei Pills, and its downstream mechanism is still unclear. METHOD: We first obtained the signal pathway of the intervention of Wumei Pill on CIM through network pharmacological analysis and then transplanted the bacterial solution into CIM mice, combined with Western Blot, HE, ELISA and other biological technology-related proteins and inflammatory factors. RESULTS: It showed that 97 kinds of effective ingredients and 205 kinds of targets of Wumei pills were screened out and the potential mechanism of Wumei Pills on CIM may be the NF-κB signaling pathway. In contrast with the control group, the results displayed that the weight, food intake, and mice's colon length were apparently decreased in the 5-Fu group, while the diarrhea score was increased. However, FMT reversed this change, and the difference was statistically significant. Additionally, FMT could improve the pathological state of inflammatory cell infiltration in mice, reduce histopathological scores of colon and jejunum, decrease the expression levels of IL-1β, MPO, TNF-α, and IL-6, reverse the activation of signaling pathway named TLR4/Myd88/ NF-κB and down-regulate protein expression, thereby exerting its anti-inflammatory activities.
